I bought the 2011 Equinox in Nov 2010. It now has over 35k miles on the odo. Only problems noted so far: needed to replace left rear turn sig light bulb, right rear speaker rattled. Gas milage (in Ariz at mostly 70 plus on highway): in town 22, on highway 29. Granted it's not the 32mpg noted by EPA, but it's fine for over 70mph. No rattles, drives mostly OK, but acceleration from start a bit lame at times. Glad I bought the car. No issues with blind spots.
Lots of room in back seat (adjustable front/rear), front seats comfortable, split folding back seat.
Move A/C vents further from steering wheel. Have totally flat rear seat when folded down (now a bit of an incline) for those long items.
